pure virtual |
Return a set of restraints equivalent to this scoring function.
Implemented in IMP::core::IncrementalScoringFunction.
|
protectedpure virtual |
Do the actual work of computing the score and (optional) derivatives. The list of all score states that must be updated is passed.
Implemented in IMP::core::IncrementalScoringFunction.
|
protectedvirtual |
Score when only some particles have moved.
Definition at line 67 of file ScoringFunction.h.
|
virtual |
Get any Particle, Container or other ModelObjects changed by this during evaluation. This is only useful for ScoreStates, at the moment.
Implements IMP::ModelObject.
Definition at line 89 of file ScoringFunction.h.
| double IMP::ScoringFunction::evaluate | ( | bool | derivatives | ) |
Evaluate and return the score.
| derivatives | if true, updates the derivatives of the scoring function |
| double IMP::ScoringFunction::evaluate_moved | ( | bool | derivatives, |
| const ParticleIndexes & | moved_pis, | ||
| const ParticleIndexes & | reset_pis | ||
| ) |
Score when some particles have moved.
This should behave identically to evaluate() but may be more efficient if it can skip restraint terms that involve unchanged particles.
| moved_pis | Particles that have moved since the last scoring function evaluation. |
| reset_pis | Particles that have moved, but back to the positions they had at the last-but-one evaluation (e.g. due to a rejected Monte Carlo move). |
| bool IMP::ScoringFunction::get_had_good_score | ( | ) | const |
Return true if the last evaluate satisfied all the restraint thresholds.
Definition at line 130 of file ScoringFunction.h.
| double IMP::ScoringFunction::get_last_score | ( | ) | const |
returns the score that was calculated in the last evaluate call
